Claims. (Cl. 242--39) This invention relates to a windin machine and hasfor one ofits objects the winding of two or more wire strands inparallel relation upon a take-up package that thereafter these strandsmay be helically laid together to form a cable.

Another object of the invention is to provide automatic means forstopping'the machine and preventing overrunning of the wire strands onthe supply packages.

Another object of the invention is to provide a simple and yet efficientbrake applying action to the supply packages.

With these and other objects in view, the inventlon' consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

These mandrels may be clamped to the horizontalbars ii at any convenient position therealong by the clamps l3 and tionofthe upper part of the mechanism shown Fig. 3 is a top plan view of theforward portion of the control lever;

Fi 5 is a front elevation of one unit of the machine showing thestructure shown in Fig. 1;

Fig. 6 is a fragmental detail of certain moving parts of the supplypackage stopping mechanism.

The winder which is the subject of this invention consists of a frame ofextended length with a driven shaft extending the length of the frame.Take-up packages are located at spaced intervals along the frame andeach is clutched'to the drive Each of these take-up packages is fed fromseveral supply packages locatedbelow and in front of the machine andmechanism is provided to stop overrunning of the supply packages uponthe stopping of the drive of the take-up package. This assemblyeonstltutes a unit complete within itself and a mulsupports extendingtherefrom. Each provides for the mounting of a package designatedgenerally it on the mandrel by means of a clamping plate I5 and wingednut US which engages the central rotatable shaft I]. The mandrel freelyrotates about the support upon bearings 98 and I9 provided therefor. Astrand ofwire 20 is wound between the heads 2| of the package and is ledupwardly as at 22 from one package and upwardly as at 23 from a secondpackage vertically above the first package. A guide may serve to keepthe wire strand 22 clear of the package above it but as the surface istraveling at the same speed this is usually unnecessary. These wir'estrands 22 and 23 (or more if used) are fed upwardly by the feed rolls25, 25 mounted in bearings along the frame which serve to meter thesupply so that the same length of wirein each of the parallel strands isprovided. The strand then enters into the groove of the traverse roll 26which is mountmachine. In the present instance as there are package fromshaft ss throughgears 90, 9|, 9:,

9 3 and 84 on the shaft 25'. This train of gears tiplicity of these arelocated along the frame to be 'drlvenfrom 'the common drive shaft whenclutched thereto.

This invention relates more particularly to a mechanism for bringing anindividual take-up package to rest upon that package having becomewinding is brought to rest I cause the supply'packtwo packages providedso there will be at least two slots in this separator. If three parallelstrands from three packages M were being assembled three slots would beused. The strands lead through these slots, and are maintained in.

parallel relation-to the delivery or take up packa e designatedgenerally 3!. The feed rolls 25, 25' are driven from the drive for thetake up may be positioned-at one end of the machine and are indicated indot-and-dash lines in Fig. 1. The. feed rolls have a surface speed alittle less than the surface speed of the take up roll. The traverse bar"may be common to all of the takeup packages along the frame and isslowly reciprocated back andforth lengthwise of the bar 28- to lay thewire in parallel relation upon the package 81-. This traverse mechanismis not shown as it plays no part in the inventive concept oi thisapplication.

The take-up package 3| is mounted upon an arbor 32 which may drop intosuitable bearings at either end and from which the package 3| may beconveniently removed. This arbor 32 is driven by means of a gear 33secured thereto which meshes with a gear 34 which is slidably related tothe main drive shaft 35 of the machine (see Fig. 4). The gear 34 has aconical recess 35 which frictionally engages the tapered driving member31 held upon the shaft 35 by a set screw 3 8. When this gear 34 is movedto the right as shownin Fig. 4 clutching engagement exists between thetapered surfaces so as to cause the shaft 35 to drive the gear 34. Theclutch gear 34 has a tubular extension 39 which is bushed as at 40 toslide along the shaft 35. A spring 4| abuts the shoulder 42 of thisbushing and tubular extension 39 and is compressed between this abutmentand the ball bearing member 43, one part of which rotates with thespring and gear while the other part is held to the shaft 35 by a collar44 and set screw 45. This spring applies sufficient pressure to move theclutch parts into engagement. A housing 46 extends over this ballbearing and spring, which housing turns with the shaft and part of theball hearing which rotates with the shaft.

The clutch gear 34 is withdrawn by a yoke 41 (see Figs. 1, 2 and 4) havebifurcated arms 48 which engage the flange 49 of the tubular part 33.The bifurcated ends may have roller bearings as illustrated. Thisbifurcation 4'! is at the end of an arm 50 which is secured to the shaftto rock in response to rotation of this shaft (see also Fig. 2). Thisyoke 41 is held to the shaft by set screw 52.

locationsuch that when the lever is in its uppermost position, such aswhen pressed by the spring 13, the operating rod 55 will engage thislatch At the opposite end.of this shaft 5| an arm 53 extends which isbifurcated as at 54 to extend along either side of the operating rod 55.

This operating rod 55 is slidably mounted in a bracket 56 at its upperend and in a bracket 51 which drops down from a part of the framework ofthe machine. This rod 55 is urged upwardly by means of a spring 58 whichabuts the lower bracket 51 and engages an adjustable collar 5-9 which isheld to the rod 55 by means of a set screw 60. This spring is under suchcompression as to urgethe rod '55 upwardly at all times. The collar 59also engages the bifurcated arm 54 so as to operate this arm when therod moves upwardly. Spring 58 is of sufficient power to overcome theclutch spring 4| so as to disengage the clutch against the action of thespring justed position by a pin 65' (see Fig. 3) which extends through aslot 55 in the main portion of the lever and is held in adjustedposition by the wing nut 51 which has threaded engagement with the pin65' and draws the head "thereof snugly up against the arm 63 while thewing nut engages the main portion of the lever 5| so as to bind theportion 63 in adjusted position. A latch 10 tapered to a point II issecured to the lever 5| by means or the screw 12 and is in a and beprevented. from upward movement under influence of its spring 58.

As the package 3| is filled with wire the roller 55 is moved downwardlymoving the lever 5| about its pivot 62 and moving the latch I0 graduallyfrom a position over the rod 55. When the latch moves beyond a verticalposition above the rod 55 the rod 55- will then be forced upwardly underinfluence of a spring 58 to rock the arms 53, 5|, 50, as a unit towithdraw the clutch and thus relieve the take-up package from furtherdriving influence from the driveshaft machine. The rod 55 is reset byhandle 24.

The supply package mandrels are both provided with bases 15 which aregrooved as at 16 and I have extended a leather thong 11 about and in thegrooves 15 of the lower package and crossed this thong as at 18 (seeFig. 5) so as to increase the engagement of the thong on portions of thegroove 15 of the next upper package. Now this relationship may continuefor other packages if desired after which-the thong has its ends 19clamped as at by means of the bolt 8| which clamp is also fixed by meansof set screw 82 (see Fig. 2) to the actuating rod 55. When the rod is'in its lowermost position the thongs "will be relaxed and will be looseabout the grooves of the mandrel. However, when the actuating rod 55moves to its upper positibn to release the clutch the thong will bedrawn up tightly and will exert a suiilcient braking pressure upon thegroove of the mandrel to stop these supply mandrels quickly and preventany overrunning of the wire strands.
